Estimate fuel savings and additional voyage time when reducing vessel speed.
Common Slow Steaming Examples
| Scenario | Original Speed | Reduced Speed | Typical Fuel Saving |
|---|---|---|---|
| Regional cargo route | 16 kn | 12 kn | 10–20% |
| Container service | 20 kn | 16 kn | 15–30% |
| Long offshore voyage | 15 kn | 11 kn | 20–35% |
Slow Steaming Operational Notes
Slow steaming is widely used in commercial shipping to reduce bunker costs, fuel consumption and emissions. Lower vessel speeds may significantly decrease fuel usage, although voyage duration and scheduling constraints must also be considered during route planning.
